The National Museum of Science and Technology of Leonardo Da Vinci sees many of the origins of science and technology. The tram was also a historical relic of Milan. I saw the tram running in 1915 and the sculpture made by the wire head in the street. The power transmission in the industrial revolution originated from the city. The porcelain bottle connecting the wire was also the product of Milan. Marconi, the famous father of radio, was also an Italian. Museum many radio learning ways, really memorable. Textile and steelmaking were the driving forces of the first industrial revolution. The engines of automobiles and airplanes were the world's leading engines before World War II. The prototype of Guangzhou Auto Chuanqi's first generation model and engine is also Italian.
